Methods of Computer Steganography that are Robust to the Active Attacks

By Materials of Scientific Report at NAS Presidium Meeting 26 December 2012

Abstract

The report presents the results of examination of the existing methods and developing some new methods of computer steganography for images and audio-signals. The problem of desynchronization between digital watermark and its carrier was studied. The analysis of effects of typical processing operations for cover signal on its amplitude spectrum was performed. The examples of the developed methods of watermarking that are robust to lossy compression, additive noise, low-pass filtering, shift, rotation, scaling, cropping, print-scan and other active attacks are given. Also the possible applications of these methods are shown.
